[0002] At present, in the construction of chimneys, slipform engineering is usually adopted to cast the side walls of chimneys. The slipform engineering generally includes a slipform system composed of templates, open frames, etc., a number of support rods evenly arranged along the side walls of the chimney, and jacks that climb along the support rods to drive the slipform system to rise. According to the use requirements of the chimney, door openings, also known as window holes, are reserved on the side walls of the chimney. During the rising process of the slipform system, the position of the window hole will slip in the air, and because the jack cannot climb completely synchronously during the rising process, during the sliding of the slipform system, the concentrated load borne by some single support rods is greater than the ultimate bearing capacity of the support rods themselves. The support rods of the window holes exposed under the slipform system are prone to deformation due to the lack of support from the chimney side walls, which makes the slipform system unable to rise or even tilt.
[0003] In view of the above technical problems, the present application provides a chimney sliding form door opening support rod reinforcement structure to solve the problem of poor support effect of the support rod at the window hole of the chimney. Utility Model Content

[0021] The utility model will be further described below.
[0022] Example:
[0023] like Figure 1 , 2As shown in Figure 3, a chimney sliding form door opening support rod reinforcement structure includes a support rod body 1 arranged on the side wall of the chimney and corresponding to the window hole, and also includes an auxiliary support rod 2 arranged on the side wall of the chimney and corresponding to the window hole. There are two auxiliary support rods 2, which are respectively located on both sides of the support rod body 1, and the distance between the auxiliary support rod 2 and the support rod body 1 is the same. A group of three connecting rods 3 are arranged between the auxiliary support rod 2 and the support rod body 1. The two auxiliary support rods 2 and the support rod body 1 are welded in pairs through the connecting rods 3 to form a triangular prism shape, and the connecting rods 3 in the same group are arranged horizontally on the same horizontal plane. There are multiple groups of connecting rods 3, and they are evenly distributed along the axial direction of the support rod body 1, so that the support rod body 1, the auxiliary support rod 2 and the connecting rod 3 are integrally welded into a lattice column form. This structure has a good anti-deformation effect. The material area is moved to a place far away from the inertia axis, which can ensure the bending resistance of the enhanced component under the same axial resistance conditions and save materials.
[0024] like Figure 4 As shown, the lower end side wall of the auxiliary support rod 2 is provided with a plurality of L-shaped reinforcement strips 4. In the present embodiment, four reinforcement strips 4 are provided, and all are welded to the lower end side wall of the auxiliary support rod 2. During welding, a section of the reinforcement strip 4 that fits the auxiliary support rod 2 is parallel to the axis of the auxiliary support rod 2. The four reinforcement strips 4 are evenly distributed in the horizontal direction around the axis of the auxiliary support rod 2, so that the projections of the four reinforcement strips 4 in the horizontal direction are arranged in a cross shape.
[0025] Before the slipform operation reaches the reserved window hole, the lower end of the auxiliary support rod 2 is embedded in the cast chimney side wall, and the entire reinforcement strip 4 is embedded in the cast chimney side wall. The multiple reinforcement strips 4 evenly distributed around the axis direction of the auxiliary support rod 2 can better support the auxiliary support rod 2 in multiple directions and prevent the auxiliary support rod 2 from tilting. The reinforcement strips 4 embedded in the chimney side wall can effectively use the chimney side wall to give the auxiliary support rod 2 a pulling force and a supporting force, and cooperate with the connecting rod 3 to resist the lateral force on the structure, effectively preventing the deformation and tilting of the auxiliary support rod 2 and the support rod body 1, thereby reducing the occurrence of the slipform system shifting to one side. At the same time, the reinforcement strips 4 have a certain supporting force on the auxiliary support rod 2 in the vertical direction, thereby improving the supporting force of the overall structure.
[0026] like Figure 1As shown, the chimney sliding form door opening support rod reinforcement structure also includes a plurality of reinforcement rods 5, which are spliced in an X-shape by fasteners. In this embodiment, the fasteners are malleable cast iron fasteners. The spliced X-shaped frame is fixed to the auxiliary support rods 2 or support rod bodies 1 of different groups by fasteners to reinforce the overall structure. In other implementations, the reinforcement rods 5 can also be horizontally connected to the auxiliary support rods 2 or support rod bodies 1 of adjacent groups by fasteners. The reinforcement rods 5 form a whole between the support rod bodies 1 and the auxiliary support rods 2 of adjacent groups, disperse the forces exerted on the support rod bodies 1 and the auxiliary support rods 2 of each group, improve the stability of the entire structure, and effectively prevent the deformation of the door opening structure.
[0027] The utility model is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model. At the same time, for ordinary technicians in this field, according to the idea of the utility model, there will be changes in the specific implementation mode and application scope. Changes and improvements to the utility model will be possible without exceeding the concept and scope specified in the attached claims. In summary, the content of this specification should not be understood as a limitation on the utility model.
